NITED STATES PATENT Q IMPROVEMENT IN SPINNING-RINGS.

Specication forming part of Letters Patent No. 158,286, dated December 29, 1874; application filed V June 13, 1874.

sistin g ot' a transverse bar, which rotates freely within the ring, and in contact with the spindle or the yarn, so as to direct the latter to the spindle at a uniform angle and tension, and which bar has its Vend bearings retained by an upper inwardly-overlapping ring. In the use of suoli transverse-bar travelers, and rings therefor, without exclusive regard to any particular one, there are practical ditlculties and objections, which it is the object ot my invention to avoid. Thus, owing to the peculiar forms of the rings adapted to the transverseh'ar style of travelers, as heretofore constructed, they have been very expensive, and difficult to temper at the parts exposed to friction without cracking or warping the rings. Likewise, no small inconvenience has been experienced in inserting new travelers when made of wire too stout to admit of their being sprung into the rings, especially with those having the travelers bent at sharp angles, or curved inwardly or outwardly, and in removing and replacing them for cleaning and other purposes.

These difliculties my invention obvia-tes or reducesin part by a sectional construction of the ring, consisting of an upper and outer shell or ring-cap, and an independent cup or lining, for rings adapted to the use of straight travelers, or those with curved centers and straight ends, and in part by a flange or lianges on the outside of the rings, constructed to lock under overhanging projections or screw-heads connected with the ring-rail, or plate resting thereon. The invention is also equally well adapted to the securing to the rail of rings which are adapted to transverse-bar travelers, having their ends bent at sharp angles inwardly or outwardly, or curved inwardly or outwardly.

In the drawing, Figure l represents a sectional elevation of a ring constructed in accordance with my invention, the same being applied to a cop-spindle, but being equally applicable to a spindle with one or two head-bobbins; Fig. 2, a lplan ot' the ring and traveler upon a larger scale, with a portion broken away to show the independent caplining 5 Fig. 3, 'a side view of the ring or ringcap, with means for securing it 5 and Fig. 4., a perspective view of a modified construction of the ring-cap. Fig. 5 is a view, in perspective, ot' the inner cup or lining detached.

A is the rotating spindle, which extends through the ring in the usual manner. The ring is composed of an upper and outer shell or ring-cap, B, and an independent cup, C, which is covered by the ring-cap, and within which the traveler or transverse bar D operates. This cup C forms a lining on the inner side and between the surfaces ofthe ring, and is formed of a steel plate, and may be cheaply made, and highly tempered and polished, and be replaced at but tritling cost when necessary,1 besides providing the best and most durable wearing-surface for the traveler, the tail of which frequently drags.

The main portion or body of the ring, including the cap B, may be made of cast-iron or other cheap metal, and the inner edge rimmed with steel. This construction lessens the tirst cost and expenses incidental to wear or injury of the rings,'the removable steel or other hard-metal cup or lining C lessening the friction and increasing their durability, and being separately removable when necessary without destroying the ring. Said cup C, which tits freely, but snugly, within the ringcap B, may either rest upon a lower rin g-plate, E, or directly upon the rail, and it and the ring-cap B are together secured to the rail, or the lower ring-plate E fastened thereto by means of an inclined flange or iianges on its exterior arranged to lock under heads or projections on the ring-rail or plate E. Thus, in Figs. 2 and 3 of the drawing, two llanges, b, constructed to form inclines, are arranged around the exterior of the ring-cap,so that, when the latter is suitably turned, they lock under heads c c of screws fast to the plate E, while in. Fig. 4 there is represented a single 2 issse i 1. The combination of the independent steel or hard-metal cup 0 with the ring-cap B, substantially as and for the purpose herein set forth.

2. The ring-cap B, formed with an inclined ange or flanges, b, in combination with the holding-down heads or projections c and the traveler D, essentially as described.
